INTRO

Penon is a well established audio distributor, cable maker and IEM maker. I have review multiple IEM from them in the past and Penon Serial as well as Penon Fan 2 are my favorite for now. Yet, none of them were bad and this explain why I always highly curious to review their products.

Today I will review the Fan2 little brother call Fan.

The Fan is priced 140$ and use a single 10mm dynamic driver. It promise a fun and versatile musicality that can please wide range of audiophile.

In a market fullfill with excellent single dynamic driver, let see how the FAN hold it's ground in this review.


CONSTRUCTION&ACCESSORIES



The construction of the FAN is made of 3D plastic resin print with a beautiful backplate made of stabilized wood panel. We can say it's a bit similar to Penon Serial built in that regard and the overall quality is excellent. Light, comfortable and small enough housing. My pair have a backplate pattern that remind me of Van Gogh ''Starry night'' paiting, which I find fascinating to look at.The nozzle is made of metal, and their a venting with metal mesh at the side of housing, which is a proof of craftmanship seriouness in term of acoustic design, this mean no dust will easily enter the housing too.
The 2pin connector is part of the housing. It's not recessed and offer versatile fit for all type of 2pin cables.




About this cable, it's a good one, as always with Penon IEMs. It's a 4 cores braided cable with solid 3.5mm metal plug. It isn't stated what material is used for the cores but my guess is high purity copper. Funny enough, I use this cable to upgrade the one included with Hifiman Svanar and find it to improve the dynamic and natural tonal balance.



In term of packaging and boxing, as always it's ultra minimalist. But what you get is plenty for 140$. The unique carrying case scream China culture and is a real beauty to look at. It include a leather pouch for the cable as well. Then you have 6 pairs of silicone eartips including the blue wide bore I find very usefull. And the nice cable stated above. You don't feel like throwing anything into trash wich is good. I'm use to get more ear tips choice with Penon IEMs, so perhaps this is the only nit picking I can do here.


SOUND IMPRESSIONS




The Fan are for music lover seeking a fun and dynamic musicality that doesn't left you hungry in term of technical performance capacity. They are not very similar to pricer, crisper and more agressive sounding Fan2, and in fact, both complement each other very well.

The Fan hit the sweet spot between maturity of tonal balance and engaging fun that have an hefty dynamic.

The tonality is a balanced warmish V shape, but not a dark one since the treble is a bit spicy and not lacking in energy. It can be perceive as W shape too since we have mid bass boost, upper mids and treble boost, all within an organic balance without any problematic overly sharp boost in treble. It's the kind of IEM that can please basshead, vocal lover and offer an highly versatile signature.

Is is one of those ''Jack of all trades, Master of none'' then? No, because they aren't boring sounding.

You don't feel out of your music with the Fan, your in middle of it.

The bass have a rumbly slam, warmed mid bass punch and thick presence. The definition and texture are a bit dark, yet the physicality and tactility of bass is well rounded in a creamy way. You have plenty of chunky thumping which benefit music style like soul, EDM, rap, R&B more than jazz and rock that need a bit more mid bass definition and well resolved presence for kick drum to be more refined in fidelity.
While their plenty of lower harmonic density for acoustic instrument to sound good in mid range, the contrabass can lack a bit of bite for well resolved lead attack, which can mix up with acoustic kick drum in a less pleasant way than digital kick which gain in beefy impact.
So we have a sirupy transition in lower mid range, or bass bleed in less poetical term. It's not a clean bass, yet not plain muddy too, their guilty pleasure going on here but in a well balanced way since the slam resonance doesn't veil whole spectrum at all and act like a glue for mid range, it stole air but not alot of resolution.
As well, it add note weight, and tend to favor fullnes of tone over brightness of presence, for that, I will suggest the bigger brother Penon Vortex.
While not a master of agility or speed, the bass hit fast enough and have meaty roundness without timbre incoherence or thin boom, it's dense and vibrant in rumble with a fast enough sustain, it's a good quality boom that doesn't have lot of grunt or texture richness, yet an addictive dynamic.


The mid range doesn't lack in density, note weight and naturalness. The tone and timbre while darken in texture and smoothed in definition edge have a warm, full bodied presence and don't feel recessed. Both male and female vocal are fully bodied and foward, with wide appealing presence that embrace the listener. Arianna Savall which sound thin and very often too shouty as a soprano sound magnificent here, since the upper mids are smooth and not too boosted, so no unbalance in loudness and the harmonic fundamental of her vocal are there, with something like Moondrop Aria (ironic naming here), Arianna sound fatiguing, tonaly wrong and screamy, which isn't the case the the Fan at all, its lush with a liquid edge to it. We don't need to hear extra texture of every lips move and the Fan understand that.
The piano sound good enough too even if not well resolve, smoothen way, with well felt note weight and warmly rounded presentation, the decay is just slight blurry so if the pianist play very fast we can miss something. Again, those are warm mids, but the lively dynamism permit a decent enough macro resolution. Tone of all instrument is well rendered and feel natural, but i feel this excell with woodwinds and vocals due to lack of clean definition edge and resolution crispness so if your more about mid range that need high transparency, good imaging and boosted presence of instruments, the Fan would be underwhelming in that regard.

The treble isn't the star of the show here, yet doesn't feel lacking or too dark, in fact, their hint of spice and brightness to permit proper snare energy, enough guitar and violin bite too. While slightly smoothen, the lower treble isn't overly damped to the point of making everything sound dark. Fan get the right balance between warmth and brightness mixing, the bass warm lower range up to lower mid range then we get more energy in upper mids and treble. While this doesn't really boost sens of resolution, it add hint of crunchyness and just slight brilliance to some hight pitch instrument like acoustic guitar. But don,t expect long sparkly decay or very airy treble since Fan doesn't extend up to 20khz and feel rolled off pass 10khz where air, clean resonance and shinny brilliance is highlight.
So, nope, it's not the kind of high that create wow effect nor will make you discover new micro details in your music, it's not the most snappy too and have slightly noisy attack sustain-decay which make percussions a bit blurry and compressed within macro dynamic, cymbals crash will be scooped in extension too.
Still, the treble sound full, not thin, and their no problematic imbalance that will distract you from mid range or bass.

The Soundstage act like a wide and tall wall of sound that surround you, so it lack deepness and you can perceive clear silence that will boost a 3D sens of spatiality.

This mean the imaging is very average and more about decent layering than crisp instrument separation and position. These aren't monitor IEM at all and tend to stick the music togheter instead of cutting it in piece for a clinical appreciation. More their instruments, less it will be easy to spot their position.

COMPARISONS



VS ISN D10 (1DD-150$)
The D10 are warmer, darker and more U shape. It's evident the technical performance of slightly bright V shape of the Fan are notably superior, especially in attack speed-control, imaging and resolution.
The bass is thicker, warmer and heavier in slam, more sustain in rumble and more boosted in sub bass than the Fan, which is punchier and more balance V, so it make it feel W shape compared to D10. Because the mids are darker, more recessed and have a hint thicker timbre due to higher bass bleed embracing and smoothing the mids of D10, in that regard the Fan sound more open and transparent, while not thin, female vocal aren't as smooth and creamy as the D10, but their presence is better define and overal mids resolution is higher and better layered, not as warmed by bass too.
Treble is darker and more scooped in edge, looser more blurry in sustain too with the D10, it dig less micro details and go muddy in busy track unlike the fast, snappier treble of the Fan, which is more open too adding minimal sens of air that D10 is lacking.
Soundstage are both similar in wideness and tallness, but deeper with the Fan. Imaging while not perfect, is notably cleaner and more accurate in positioning due to extra definition edge and less blurry separation.

All in all, while the D10 is perhaps a legit basshead IEM, it can't compete in tonal balance nor in technical performance with the 10$ cheaper Penon Fan.

VS MOONDROP KATO (1DD-190$)

The Kato is more neutral, cleaner sounding and more detailed. It sound more technical, and have greeater focus on instrument presence and texture details than slightly warmer Fan. The Fan is notably more V shape and punchier, it sound less distant in dynamic, more bodied in timbre and more dynamic and engaging in musicality.
The bass is better resolved and define with the Kato, separation is clearer too, but the punch is lacking, and the sub bass is more textured, leaner and deeper in extension, so a hint less warm and boomy than the Fan. Mids are cleaner, more open and detailed, layering is superior as well as timbre is more realist in texture with the Kato, it's thinner too and female vocal can be a bit too loud in pinna gain. Both male and female vocal sound thinner and less smooth the Fan, tone have more fundamental with the Fan too, which warm and thicken presence which is dryer with the Kato. Treble is notably faster, fuller and richer with the Kato, it's cleaner and more extended and airy. Level of sound info is greater for sure with Kato which confirm the superiority of it's driver.
Soundstage is wider and taller with the Fan, but way way deeper and cleaner with Kato. Imaging is from another league with the Kato, bot in layering and sharp positioning.

All in all, while the tonality keep me distant from music and emotional engagement with the leaner colder sounding Kato, their zero doubt the technical performance is from another league.

VS PENON VORTEX (1DD-220$)

The Vortex is brighter, more neutral, less bassy and offer a more vivid and detailed treble. The is less warm in slam and more textured and well define, it's faster and tighter. Mids are thinner with more resolved presence, it have more bite and edgier faster attack. Mids note weight is ligther with instrument like piano. Upper mids are more boosted so female vocal are more fowards and agressive. The treble is crunchier, brighter, fuller and more extended, electric guitar and clavichord sound less scooped in definition and have a more abrasive and lively presence. Highs are clearer, cleaner and better separated too.
Soundstage is wider and taller with the Fan but less deep due to thicker mid range and closer center stage. Imaging is superior with the Vortex due to brighter resolution and better high pitch instruments and sound separation.

All in all, you pay 80$ more for extra technical performance, a brighter resolution and more neutral tonality with the Vortex. Personaly, i find the musicality of Fan more laid back and pleasant, especially timbre wise.

CONCLUSION




I'm I a Fan of the Fan? Yes, absolutely, these are easy to love and cozzy to listen to.

The Fan offer a fun and safe tonality with natural timbre, authoritative bass and lush mid range that will sure please vocal lover.
While no master of technical performance, the FAN are still competitive single dynamic driver IEM in sub-200$ market, this is due to it's beautifully balanced warm tonality that offer a big and immersive spatiality, great dynamic rendering and engaging bass slam.
The Penon Fan offer a versatile musicality that will please wide range of listeners, while warm sounding, they aren't plain dark or lacking in treble energy when needed.

If like me you are allergic to thin mids or harsh upper mids and tend to favor natural timbre that have good density, the Fan might be the laid back sounding IEM you want to get lost in for long hours.

Recommended!

The Penon Fan IEM
I have to admit that I’m not sure that the Penon’s Fan sound is simply better than many IEMs in its price bracket, or I’m just a Penon tune fanboy? Maybe a little of both, but most likely it’s unique and special in the world of recently introduced full-range dynamic drivers. The packaging IEM storage “box’’ being covered with a woven thread painting is the first clue as to our “different” experience. Such wild magical energies portrayed in threads suggest that we have stumbled upon something out of the ordinary.

A story
So let’s say you went on vacation, the box was laying on a bedside table and your housekeeper was inquisitive. She took the curiosity one step further and looked into this wild box, what would she find? Grabbing ahold of this light brown tassel, she would then lift the lid…….and discover the entire box liner was lined in black velvet. Then in the center she would find the two small noise producers. They seem to be put away like something incredibly precious. She knows what these are from previous experience, yet to lay her hands on the IEMs themselves they are incredibly smooth. To gaze upon the faceplates shows another attention to detail, the stabilized wood design, showing each Penon Fan to be utterly unique. The IEMs match this little box, the craftsmanship is apparent……..these are like little art-pieces even before you put them in your ear-holes. But the curiosity continues and she grabs her phone. She places the Fan IEMs into her ears and is surprised, but more than that, the music is 100% completely accessible to her. This is as close to a consumer tune as Penon has ever offered. It’s downright fun, it really is. Except there is more…….they have carefully orchestrated a soundstage, and even though it is the quintessential street tune, everything is accounted for within that stage. So after that short bout with inquisitiveness, she puts the IEMs back in their case, and wonders how much they cost. Surly they must cost a lot, maybe as much as TV, she thinks? She will definitely ask about them when you return. End of story.

The story after:
This story goes about to express the creativity found with Penon, why they don’t include that same case with every IEM they make I’ll never know, but the cloth covered case is utterly unique. The fact that the Fan is not a brand new release is another area of curiosity for me. The Fan came out in January of 2021, and since that time there has been a couple other releases. We even already have the Fan 2 which came out last month. Yet, as always Penon never travels down the same path twice, there is an adventure to be had, the Fan is a $139.00 art statement. Where the original Fan has a V shaped tune, the Fan 2 is the most neutral IEM Penon has ever accomplished. The Fan 2 is $279.00 also. So? They are not at all related except in a wild to behold midrange demeanor. Why am I even talking about midrange (to start) with a V shaped signature? Because Penon. Penon are the kings at this silky smooth midrange that becomes the endearing aspect of any Penon IEM you buy, even this one. In fact during my testing trials I was bombarded with Planar IEMs this year, and when I first tested the sound of the Fan IEM, it was right after a modern day Planar, and you know what? This little Penon Fan has a bigger midrange expansion physically into the midrange soundstage, and a more accessible style due to this. Penon does’t make a Planar, yet while Planar IEMs are simply different in there presentation (and wonderful) I was shocked and this random side-by-side! I really was. It was one of those times when you put an IEM in your ears and you’re surprised at what you find. That’s how life is at Redcarmoose Labs, just a bunch of IEMs burning-in on a table top, waiting to be auditioned for the first time. They will often be randomly sided with another IEMs just by chance, as I only have so much time and so many burn-in rigs. But Planar IEMs are the rage right now, so much so that there is a chance that this single full-range dynamic driver could get overlooked. And that my friends would be a travesty, really it would. If anything with all this Planar business taking place there needs to be compreble addition to your collection which can stand-up perfectly comparable to Planar playback, at even less money, offering a stand-up tune which parlays perfect timbre, you know the timbre advantages that are expected from single full-range dynamic drivers. So let’s get started shall we.



Penon Audio:
Penon is probably more like a craft beer maker than a big conglomerate manufacture like Budweiser? While both avenues are a route to your IEM destination, big manufactures mass produce printed metal shells like copies of copies of copies. Where Penon is more of a music enthusiast brand making IEMs which reproduce music with a noticeable character and stance. Penon doesn’t just make IEMs. Besides the Penon brand, they are a retail house that currently represents/sells 120 different audio brands. Not only a retailer but a renowned cable builder, making 44 different cables/adaptors right now. Penon also currently manufactures 10 separate earphones as of late. With a history going back to 2013, Penon is the logical result of years in the business. With a Penon product there is no middle-man……as this is a factory direct purchase. Penon are simply more grassroots in demeanor. Such focus of intent expands even to their whole IEM line. Where some big companies make all styles of sound signatures, Penon on the other hand continues offering a subtle variation of the same tune. Such differences may be indicative of driver methodology creating creative differences in sound? Still Penon is always driving in a singular direction it seems. There is no room to make an odd-ball tune or throw stuff against the wall and let the buyer be the experimenter. Here we are gifted with another reiteration of the Penon House Sound. Strangely of all the Penon IEMs I’ve heard, this is the most V shaped. So far I’ve heard the ISN (a subsidiary of Penon) D10, H40, H50, the H30 and ISN EST50. As far as Penon goes it’s the Fan 2, the Orb, the Vortex, the Serial and the Globe. So are these all related? They are with often ISN being more bass focused and Penon being more midrange focused. That doesn’t mean ISN are all bass and Penon are all midrange, in fact these personality traits are way more subtle than you think, yet the are there none the less.


The accessories:
Coming with 6 pairs of regular ear-tips, Penon has also included an extra 7th pair of dual-flange tips. One wild fact is the size of the blue L size is the biggest ear-tips I’ve ever seen. As shown in photo, you also get a small pouch and great included cable.

Cable:
Included a 3.5mm cable and 2Pin 0.78mm 4-strand silver plated single crystal copper cable. The included cable offered very specific benefits as to sound, often I would refer back to the included cable during cable tests finding it well balanced and detailed.


Cable comparisons:
A) Included Penon Cable
B) ISN G4 Cable
C) ISN S2 Cable
D) Totem Cable
E) Penon Obsidian Cable

As to the five different cables tested, part of the reason this cable test section is in the beginning is we can learn many aspects of an IEM through how it reacts to cables. Meaning because this is a 10mm and has a specific personality, more can be revealed through cable changes. Starting with (what I thought) would be a good combo, the ISN G4 cable, a composite of graphene, gold-paint silver plated OCC, was in fact thick. Thicker in girth (than the included cable) the G4 was nice, and while the size of stage was apparent, the trim and seemingly thinner sounding ISN S2 cable seemed the perfect balance in the end. Part of the the fly in the ointment here is I’m also trying to get cable personalties figured out through changing amp sections on the WM1Z. Such difference in amplifiers could in-truth be perceived as cable changes. So in due diligence, I finally switched the ISN modular plug to 3.5mm single ended, so it would use the same amplifier as the included cable tests and ISN S2 tests. And while the ISN G4 cable was entertaining, there was a slight brightness in the 5 kHz peak that was often noticeable? So rolling back to the 3.5mm included cable and 3.5mm ISN S2 proved to be a great test, where eventually I landed on using the S2 simply because it offered a cleaner midrange and slightly more forward and brighter rendition than the included cable. This still would have to be user taste, as in multiple days of cable testing I found the included single crystal-copper silver plated 3.5mm cable to be ultimately balanced and detailed enough. Meaning in their wisdom, Penon included such cable in offering a set-up with the Fan that would be ultimately well rounded and perform admirably with the broadest range of equipment and most music genres. So when you get the Fan, sticking with the included cable leaves very little extra to want from cable change-outs. Also depending on your hearing, it may in-fact be the perfect cable. I on the other hand migrated to the 4.4mm balanced S2 cable, finding a certain clarity and balance that I wanted to stick with. The remainder of this review is with this set-up. Yet I did so much listening with the included cable, really there is very little difference here in regards to the Fan’s personality. Just think of the ISN S2 as keeping the basic Fan traits!

Totem Cable:
For fun I rolled back to the Totem cable just due to curiosity. I must be extra curious, as to be honest I did this on multiple days to check the results. For the most part it was an improvement and really showed what the Fan was capable of. Seeing deeper into the soundstage, instruments started to appear larger and offer higher in detail to view tone constituents. And while at the end rolling back to the mainly used $79.90 ISN S2 cable showed differences, they were cleaner and offered a just different personality from the $799.00 Totem. Surprisingly the Totem is more for BA IEMs and frankly I was skeptical as to its performance with a 10mm full-range dynamic driver, but, yes it was maybe the ultimate cable for the Fan, even though some may find it ludicrous to match a $799.00 cable with a $139.00 IEM?

Obsidian Cable:
This was interesting as again we meet-up with thicker displacement of stage, much like the G4, yet the 5 kHz peak and 8 kHz were reduced due to the lack (not a drop) of silver added, which resulted in a smoother more congealed together rendition of music, where again just the stance of the general nature of the Fan, goes to show it needs the slight extra boost in upper midrange and treble detail along with the musical itemization and separation form a cable like the ISN S2 or the included cable for that matter.

Penon FAN 10MM Single Dynamic Driver 2Pin 0.78mm HiFi Audiophile In-ear Earphone

Specifications
Brand: Penon Audio
Model: Penon FAN
Dynamic Driver: 10mm
Sensitivity: 102dB
Impedance: 23Ω
Frequency response: 20Hz-20KHz
Plug: 3.5mm




Sound:
I could continue all day with cable changes but I would most likely lose you a reader. Yet the cable tests truly reveal how the make-up of the Penon Fan is slated. It’s a full-range DD that offers a V signature, and of course that means both an add to the deep-end as well as the treble. Yet due to a carefully orchestrated tune combination, the Fan somehow bypasses any of that feeling of early roll-off on the lows often found with full-range DDs. While never exactly dull due to the pinna gain starting at 2.5 kHz. The Fan continues (after a dip) to a gain at 5 kHz then to another dip, ending peak at 8 kHz.

What this affords us listeners is a perception of an adequate and fully engaging midrange complete with that upper midrange imaging that is so crucial to never having that feeling of being too dark. It’s just right. While my cable tests proved it walks a careful and calculated line, such a tune is truly flexible in offering a brighter rendition with the ISN S2, or a darker experience with the Obsidian cable. This is the tell-tale Penon sound in the end, yet it’s for those that want a more consumer tune. Now the wild part is due to the technicalities and tune, it’s one of the best consumer tunes I have heard, right along with what Sony has done in this part of town. Yep, I’m saying this about a $139.00 IEM? You would have to hear the Fan to truly get what I’m saying here, as graphs only tell part of the story!

The Bass:
My gosh, the bass. With the right files the tones are a spectacle, more curtailed than the ISN D10, but super-dramatic none the less. Where the D10 is a single full-range L shape curve, here we are offered a faster transient yet still a deep, full-on bass experience. It’s most likely the soundstage character of this bass, that it’s fast and explosive, gaining even more ground the more you listen. You know where this is going right? The coming talk of decays and fall-offs, the candy treats that come only with a DD driver experience. The cohesiveness and the unions of frequencies that only a full-range DD can do. And most of the time I’m down for a hybrid experience as I truly think hybrids normally can do more. Yet here there is a separation, where the stage is expanded and not just for the bass, the expansion follows up into the midrange and treble too? But surprisingly the charm is just how dexterous the bass is. Meaning in rock songs the bass bumps and fills in the groove ever so carefully in place, only to show another character in orchestral personalty, jumping and going out to the farthest reaches of the stage. In fact it was these far off thunder strikes that endeared me so! The ambiance of the lows, the deepest tones, while still seemingly able to about-face and transient into exactly what the song called for? It is the Fan’s ability to cater to whatever you throw at it that becomes of interest. That yes, it’s well rounded and plays many different file qualities and music genres, but what it does with well recorded music is what’s truly valuable. Meaning get the Fan your best tracks and it will show you where your money went.

Midrange:
My cable experiments were somehow most focused in the treble/midrange? What does that mean for the listener? Well first off this is a Penon IEM. That means that they would never think of releasing boring mids. There is that trademark Penon silkiness and midrange charm, even though this is a V shape signature. But the next thing is that they have brought up those peaks just to the right part of town, and depending on the cable, or DAP synergy, there is always the chance of the brightness being too much. Still there is an element of predictability here, where once you find your cable and DAP, there are no more shocks. Yep, there is an even, complete and correct display of your entire library. While there isn’t the vocal forwardness of a vocal specialist IEM, the vocals leave nothing more to be desired, at least for me anyway. Female vocals remain fully engaging and entertaining, never even questioning the Fan’s ability in the least. Nothing is ever dull or heard as lacking luster while at the same time this would be considered a warm IEM. It’s what I call spacial and warm, meaning through separation and imaging is where we get our kicks. Often due to the asked-for-price we seem to connate soundstage value, but not here, it’s all presented and admired for what it is. There is a way the Fan presents the music that is like an actual fan, where maybe that is where they got the name? The music has this subtle essence that it’s introduced and falls away in the gentlest of manners…….this ability for the midrange to project these separations out into the stage, then roll them back, as maybe they were first intended by the performer?



Treble:
The treble is the most difficult to describe here. That is why I avoided it till last, for no other reason. It’s probably the imaging that makes it work, of course there is still all the standard treble tunings, like the strict sibilance dip at 6 kHz. The tiny and sharp peak at 8 kHz is there and sounds just like you would think it should sound, just about the same level as the 5 kHz peak, yet more tiny in size………and then……the treble is gone! Yep, a roll-off creating a relaxed form of display yet fully accessible and entertaining. First off, I’m just like the next guy, sure I believe that treble complexity and information up-there is what separates the TOTL IEMs form the beginner sets. Still the way it’s done here leaves nothing more to be desired. Penon understands the treble needs of their buyers. What is occurring is the perfect tonal balance, actually I’m totally surprised just how well done this treble is. Part of the reason is it’s even. That may sound simple but it’s not, if it was simple we wouldn’t have all these (other brand) attempts at it which fall short. They miss the mark due to offering a set of frequencies which ultimately come-off unnatural in replay. Not here!

I could place note-weight as one of the top priorities to the success here. Due to the character of treble replay each and every ounce of playback has even and correct instrument and vocal weight. That is part of the magic. The other parts happen by simply having artifacts be projected out into the stage. These small items of treble frequency be it cymbals or hi-hats offer shape and tone. If they somehow make it farther out and show separation out-of-the-mix, then they not only perform their duty as a rhythm instrument, but show correct timbre.



Build quality:
Look at it! 3D printed out of translucent blue. Yep that shell isn’t black, it’s a style of transparent dark blue. The nozzle, the most perfect invention of metal, with an inset screen and proportionate size. The nozzle-angle fit me perfect, note the small lip incorporated into the metal nozzle creating a grip for tips. Though I migrated from my standard wide-bore silicone ear-tips to the included “green-center” tips and they stayed on for the review. Note the stabilized-wood faceplates, possibly they resonate with the driver frequency to add character. The FAN and PENON name is embedded in resin, and each IEM is slightly different (stabilized-wood) with some more orange and some more blue or purple. This air-vent is usually wide and covered with a style of almost nozzle screen material, it’s a piece of aluminum with holes drilled through it. The Fan weights in at a feather-weight 3 grams a piece, forming a medium small build which just adds to the comfort. The 0.78 two pin holes are mounted flush with the sides offering easy cable change-outs. Really in so many ways the build is thoughtful and about as close to perfect as you can get.






Cable build quality:
Note the 2 pin housings are delineated with stripes both blue for left and red for right. The ear hooks are slightly aggressive, and while the cable in general has its tangly moments it’s 98% great. This greatness comes from gorgeous all aluminum build as far as the 3.5mm plug housing, two pin housing and cable splitter, yet the chin-cinch is a plastic bead. The plug itself offers two separate levels of strain relief as well as carbon fiber inlays to the 2 pins, the cable splitter and 3.5mm housing. The single crystal copper has what sounds like a light silver plating and sonically arrives at a balance to which it perfectly matches the Fan’s tone. A few IEMs seem to be mismatched with too bright of cable only to be better matched with copper, though here it was fully thought out. Such a cable brings about a warm lush demeanor fully complementary to our Fan's IEM tone.

Stage:
While organic and rich, this style of stage goes about its business in the most effortless of ways. In medium height, and depth, the width is something else, again going about the technicalities here doing what the Fan does. A sound space afforded by the seemingly correct natural formation of musical formations into the stage.

Timbre:
Just right, of course. Where do I look? Such test tracks which hold guitar chords will show me the harmonic overtones, just the way they can arrive being correct and true…….sounding right. Such qualities are why we buy single full-range DDs. But in fact DDs are only as good as the combination of other qualities. Meaning of course timbre is spot-on, but that would be worthless if the tune wasn’t right. And of course the timbre and tune wouldn’t be as valuable if the stage and imaging wasn’t correct.

Transients:
Transients are partially responsible for imaging, which can also be affected by the frequency response. But when a balance starts to take place, each and every note is positioned as would be seemingly natural, as if never questioned. And this goes to offer two things for the listener, one a thrill as to hear examples of fast transients in attack notes, but also to experience the true fall-off of the musical events DDs are known for.

Detail:
While the experience of note weight and warmth, eludes to a slight compromise in experience of detail, the magic here is in the decays….the decays and tone. There is a positional detail in reverberations that slowly becomes the charm. The way they are scattered-out only to be viewed in the most perfect of places……….romantically formed with-out the need of extra detail. Yet when met with fast accents, the separation and change-ups becomes of interest, showing that the Fan gives as clear of view as you could ever need or ask for. While these aren’t hyper detailed examples of the IEM art, the transients and agile responsive change-ups go about to gift a pleasurable and easy-going listen. Though due to the midrange and treble FR placement there is way more fidelity than you would guess. At times it’s about guitar harmonics being full and natural which supersedes detail.

Conclusion:
The Fan is way better than I thought. Is it me and how I relate to the Fan, or is it the product? Is the product wildly superior than many in the $139.00 range? As said earlier, this may be a combination of both, being I relate with what Penon is doing right now, they are continuing and using know-how they have learned along the way to make a competitive product. They know how to make IEMs well at this point in time. But more than that, Penon has a house sound that they have developed and continuously reintroduced as their own. It’s a thing, but often at the same time hard to pin-down. As they portray this sound inside of every new IEM tune, yet the over-all tune represents slightly different frequency response curves. It’s almost like this velvety midrange that simply can't keep away, seemingly part of the whole line, yet not always noticed right off. That’s kinda how the Fan 2 was, where I did a whole review only to come back to the Fan 2 weeks later to finally hear how it was related to its family. At times you need time off and to distance yourself from IEMs to notice such things. In reviewing at times we get to close and can’t see the forrest for the trees. And talk of the Fan 2 may have you wonder, meaning a new edition must be better or new and improved or something? When really the Fan and Fan 2 must somehow be related, even though the Fan number 1 is V shaped and the Fan 2 neutral? All I can say is maybe three weeks after this review I may perceive how the Fan and Fan 2 are more related. At this point in time they are almost opposite, in that the Fan doesn’t fit quite as deep, as due to its sound it doesn’t need to. The Fan is a bargain the way DDs can sometimes cost less for the amount of sound they produce, less complicated, less parts. Because we all know a correct tune at times costs nothing to produce, if all the aspects fall together. It’s just that I would have never guessed this single IEM could be so correct? The soundstage, the speedy bass, the midrange and treble imaging, the bass imaging! It’s all here, better than you would guess by focusing on the price. As upon close inspection, there is nothing missing here, the only thing missing is you and the Fan IEM together.

Introduction

Once again I am going to review a product from Penon Audio. This is the Penon FAN, a 10mm Single DD from the audio products brand that is known for having a very clear idea about how to tune their products. On this occasion I am faced with a review of the brand's U-V sound. I have said that Penon has a preference for an organic, silky, warm sound, with softer, extended treble and a lot of passion. And indeed, all of that is present in this model, but with a touch more enjoyment and a dash of daring. Previous tunings of Penon products I've tried have been more balanced, while in this case, the profile is more pronounced, with a more prominent sub-bass and more emancipated upper mids, without losing the treble extension and velvety character. Without a doubt, this is a great alternative to the U-V models because Penon persists in containing a great timbre, its sound silky, musical and very pleasant. Let's take a look at what this Single DD is able to offer to all fans.



Specifications

• Driver Type: 10mm Dynamic Driver.
• Frequency Response: 20Hz - 20kHz
• Sensitivity: 102dB
• Impedance: 23Ω
• Jack Connector: 3.5mm SE
• Capsule Connection Type: 2Pin 0.78mm

Packaging

The presentation of the Penon FAN is curious. They came in a small, plain, white rectangular box, but inside was another beautiful box lined with textile, with a patterned motif that might be reminiscent of ocean waves. This box, eminently in blue, has a copper-coloured cord, with a knot in the middle and the strands separated from it, as a means of opening the lid. The inside is lined with black velvet and features the typical Penon envelope-like brown leather pouch and two zip pouches containing the silicone tips. Specifically, the complete contents are as follows:

• The 2 Penon FAN capsules.
• One 3.5mm SE 3.5mm cable and 2Pin 0.78mm 4-strand connection.
• Three pairs of clear silicone tips, with light green core, sizes SxMxL.
• Three pairs of blue silicone tips, sizes SxMxL.
• One envelope-style leather pouch with clip closure.

I insist that the packaging is surprising, because of its mix of originality and beauty. In reality, though, the whole thing is rather simple. I miss a slightly more rigid carrying case than the leather envelope and some sets of foam tips. But I must highlight the outer box, very practical for storing more IEMS and the blue tips: they are possibly the biggest tips I could find, something that users with wide ear canals like mine appreciate a lot.



Construction and Design

The capsules have been manufactured in resin using a 3D printer, while the outer face uses a stabilised wood panel. The pattern on the outer face, with a blue background and light wood grain, offers an eye-catching beauty, further highlighted by the gold lettering of the brand and model on each capsule, PENON on the left, FAN on the right. The shape is classic semi-custom, with a rounded African continent silhouette. Its thickness is accentuated and a relatively large breather valve can be seen at the top end, covered by a perforated mili-metal grille. On the other side of this corner are the two holes for inserting the 2Pin 0.78mm cable. These holes are integrated into the resin body itself and have gold-plated connections and both are shallow, so that the cable is completely smooth and glued to the capsules. The whole body is very rounded and the inner side has smooth curves without the protrusions that fit our ears being prominent. On the contrary, the whole surface is smooth and pleasant. At the bottom, although the capsules are dark, they have a slight transparency that allows us to intuit the components inside, albeit very subtly. The mouthpieces are metallic, silver-plated and are inserted into the body. They are 5mm long, have a ring located slightly beyond their middle, although their shape is quite regular, like a cylinder with a diameter of 5.5mm. They are protected by another millimetrically perforated grid.
The cable has 4 intertwined strands of what looks like silver-plated copper. The connector sleeves are cylindrical, with a checkered pattern in black carbon. The 3.5mm plug is gold-plated. The splitter piece has the same pattern, but the checkered part is a bit longer and has two thick black plastic rings on its edges. The adjustment pin is a black hard plastic sphere that fulfils its role well. The sleeves of the 2Pin connectors retain the mixed carbon pattern and black cylinder design, as well as having appropriately coloured sunken rings, in red and blue, to identify the channel. The two pins are mounted on a piece of white plastic with an indentation in the middle to identify the outer face of the cable.
There is nothing strange or excessively new in the design of the FANs, but I must comment that the stabilised wood panels give them a superior appeal, their motif being one of my favourites among the brand's headphones and, why not say it, among the competition as well. As usual, the construction is excellent and both the shapes and the design are very well used for the purpose of the product. The cable fits quite well with the sound profile, only a cable with more silver could be used to splash the treble a bit more, but I can't complain, and it doesn't feel like it needs to be changed. The only downside is that it doesn't have a choice of balanced plugs, something that would give a plus to a pretty decent cable.



Adjustment and Ergonomics

The slightly longer and thicker metal mouthpieces than the integral resin caps ensure a shallow insertion, which could be medium if smaller tips are used and our ear canals allow it. Using the standard wide outer canal tips, the seal obtained is very occlusive, resulting in very high isolation and comfort. Moving on to my foam-filled hybrid tips, the comfort is maintained and the capsules are fixed, remaining almost floating, but without being able to move one iota, thanks to the great fit inside the pinna. It is a shape that adapts to my morphology like a glove, no rotation is possible and the set of guides on the ear of the cable in conjunction with the shape of the capsules, both the inner side, as well as its external shape, form a highly comfortable set, very light, that can be used for hours, even being suitable for movement, running or walking. In addition, the cable is very flexible and has no tendency to take shape, which increases the freedom to use it outdoors without any problems.



Sound

Profile

As I mentioned in the introduction, the Penon FANs have a U-V profile, where the sub-bass is pronounced, along with the high mids and early treble. Still, it's not a bright profile and despite the noticeable gain at the low end, it doesn't have an unbalanced curve either, but rather Penon's trademark smoothness persists. The treble is never over-excited, but on this occasion has a more accentuated brilliance. Again, I emphasise Penon's control over this part to ensure a pleasurable listening experience, adding a high enjoyment factor on this occasion. Possibly, a clear example of how Penon is able to tune such a profile without anything sounding aggressive, without losing musicality or the silky nuance of its sound. Something that makes them great to enjoy our best electronic music for hours on end, to give an example of a style that I feel suitable for these IEMS.



Bass

Without a doubt, Penon bass tuning is synonymous with quality. And the FANs are an example that elevates this statement, if possible, even more, given the more emphasised level of the low end that this model possesses. In addition, it is a dynamic driver, something that adds superior value to the sound of this range, both for its naturalness and its depth. The response of this range starts with a very sensory perception of the sub-bass. It is able to move a large amount of air, something that achieves a natural sonority, with the necessary darkness, a highly noticeable and very pleasant power. This is my preferred response. Sorry, BA drivers, there is nothing to do when the LFOs come from a DD as well tuned for bass as I find myself here.
Another highlight is the texture, which is rough, purring, persuasive and very eloquent. It has a great descriptive capacity and a roughness that is as attractive as it is soothing.
As for the level of punch, these feel very effective, very well resolved, combining a remarkable relationship between dryness and moisture, enough to maintain restraint, but without losing juice in the execution of the drums. Their power level is high and it is the point that adds viscerality and that fun factor that is undoubtedly necessary for many musical styles. On the other hand, it is not a bass that lingers, but it is also able to stay in the room long enough to be savoured, without colouring the rest of the frequencies. Although, I can't deny that its level of presence is felt from the very first moment.
Thanks to the depth that the driver achieves, the bass has great layering, as well as an important ability to generate different planes. It's also very effective when you demand speed in the execution of complex, unfiltered passages. The Penon FAN is not one of those IEMS that get lost in the bass scales or sound vulgar, far from it, lost. They can handle a high level of sound pressure without losing control. In fact, their level of precision and resolution is very high, even if the excitation is as high as in this case. And this is never easy to handle. As outstanding as its emphasis.



Mids

These are perhaps the first IEMS with a clear U-V profile that I have heard from Penon and I wondered how they were going to approach the mid-range. And the result can be summed up in one word: very pleasant. It's certainly something the brand doesn't lose sight of and, in this respect, the midrange enjoys a slight warm colour, is hugely harmonious, musical and pleasing. The presentation is smooth, subtly delayed, but still virtuosic. There is no doubt that if the bass is powerful, vocals can take a back seat. Yet the driver has such good resolution that, even in these extreme cases, it is able to demonstrate dexterity in the presentation of the mids, male voices included. Because of the shape of the curve, female voices are treated more favourably and are slightly closer. But if there is one thing to note at this point, it is that despite the distance we are talking about, the descriptive capacity of the strip is still very high. It is not a V that sends the mids to the background to forget its treatment. Quite the contrary. It is a tuning that points in this direction, but it would be unfair to ignore the fact that the quality of the mids is not at odds with this slight distance. Moreover, as usual with Penon, there is always a touch of passion and exuberance in this section to add zest to the whole.
Continuing with the second half of the mid-range, the FANs are the perfect example of how to excite this band without bringing negative effects. If it weren't for the graphics, it would be difficult to comment on the emphasis in this section. Because their treatment remains safe, smooth, musical and free of sibilance. The tuning, in this respect, brings what is needed, clarity, sparkle and a point of joy to the sound. And so it is, the mids are helped by this burst of light, which broadens the perception of softly exposed detail, to gain in transparency, offering a sound with a restrained brightness that counterbalances the warmth of the whole. Possibly one of the most melodious and delicate mid-range I have ever heard in an IEMS of this tuning.



Treble

The Penon Fan's also enjoy the kind of treble that is a trademark of the house. It's true that this time there is a higher initial sparkle, but it's also true that everything is under control and, again, I have to talk about smoothness. These are not nuanced trebles, which have lost their light and energy through clipping. It's the treatment I'm talking about: extension and musicality, the search for sound with brightness, but pleasant above all else. And so is the upper range of the FANs, subtly sparkling and controlled, with rounded trebles that bring sweetness while doing their job effectively. In this way, the brightness is ephemeral, with a quick glare that is never piercing, spreading well, but without echo, or over-exposure. The control roll-off exists, but therein lies the wise tuning of the ensemble: it is not a clipping that impairs the spaciousness of the zone, but smooths it out to stretch it subtly into the air zone. In this way, the treble is present, relatively broad, yet pleasing, subtly crisp and equally melodious as the rest of the range, but with a hint of initial spice that adds liveliness to the sound, as well as hinting at more obvious detail. In this respect, I have found that fonts can play an important role. I used several dongles to test the FANs and found the best synergy with the E1DA #9038D, getting plenty of body in the lows, great musicality and sweetness in the mids and moulded, present, descriptive, controlled and melodious highs. While with the xDuoo Link2 BAL the sound has not been so rounded and more oriented towards the high range.



Soundstage, Separation

The scene has good depth and is predominantly frontal. Although the amount of height is adequate, the sense of laterality is better. Thus, the image has a semi-spherical shape, with an oval tendency, whose perception of three-dimensionality is not able to completely envelop the listener. This creates a scene that is quite natural and where the sound does not escape from the head, which is good for reproducing music in a realistic way. Vocal and instrumental positioning is adequate, well-drawn, though not exactly defined.
There is no congestion whatsoever, though the elements feel cohesive for the musicality of the ensemble. Separation is better than average, but these are not analytical IEMS. The driver has sufficient resolution to expose micro detail, but perhaps the large presence of bass can mask it at times.



Comparisons

TFZ Tequila Pro

During the review of the Penon FAN I was thinking about what I could compare them to and I realised that they had a similar profile to the TFZ Tequila Pro, but more musical. The FANs are currently priced at $139 and the Tequila Pro at $179. Both models have a very different design, from the semi-custom shape of the FAN to the cylindrical capsules of the Tequila Pro. Both have good ergonomics, but the shape of the FAN is more universal and fits better. They also weigh less. The TFZs might only be more suitable for those who prefer flatter capsules.
For the rest of the accessories, the level is similar. I think the Penon cable is better and more manageable.
In terms of sound, the signature is similar. But the emphasis changes slightly on both. I feel a superior sub-bass enhancement on the FANs, while the TFZs are slightly brighter. The FAN's signature is warmer and more musical. The TFZs are not purely analytical, but the subtly superior mid-high and upper treble enhancement gives them a point of more sparkle and brightness.
TFZs, as usual, are more sensitive and need less power to sound good.
The bass of the FANs is slightly bigger. From the sub-bass, you feel a superior roughness and more punch. Their texture is more perceptible and descriptive. This time around, the TFZs are drier and tighter, possessing a more restrained and subtly faster punch. You could say that the bass of the TFZs is more disciplined, while it is more visceral and fun on the FANs. On the other hand, in all other characteristics, there are more similarities than differences. Both in terms of sub-bass rumble and texture, I prefer the FANs.
Both IEMS are very similar in their curve and this is demonstrated in the midrange. In the sense of mids recreation, distances and separation, this is where these similarities are noticeable. In the timbre there are slight differences generated by a more accentuated brightness in the TFZs, while the musicality, smoothness and warmth of the FANs reigns supreme in the range. Thus, the sound is more passionate, harmonious and a little thicker on the Penon. The TFZs feel cooler and subtly more defined. The higher brightness point serves to isolate the centre notes a little more, which are described as a little more separated and also clearer. This does not imply a detriment to the detail of the FANs, but it is more evident in the TFZs.
Much the same is true in the treble. There is more finesse and a higher point of emphasis in the TFZs, while the high notes in the FANs are more rounded. Both the control zone and the extension of both sets is similar. But the comparatively brighter and more analytical character of the TFZs offers subtly more evident and clearer treble. Although, in reality, there are not so many differences in their extension or draw, just that slight emphasis and a finer note profile in the TFZs.
Reviewing my notes on the TFZs, I noticed that the scene and image is described in a very similar way in both IEMS. The level of laterality, height and shape are similar. I think there is more depth in the FANs, while the TFZs have better separation, thanks to that sparkle point and finer definition. I would venture to say that the scene is bigger on the FANs, but not by much.
A fairly similar curve, for a different tuning and timbre in both models. While the FANs go for a more descriptive sub-bass, with better texture and presence, as well as a harmonious, musical, passionate and rounded sound, the TFZs have a bit more sparkle, light, definition, as well as finer notes. These differences can make you choose one or the other, without fear of making a mistake, because both are great products. But the price/performance ratio of the FAN is higher. Thus, the sound of the Penon is, qualitatively speaking, equal to that of the TFZ, but at a lower price. If you add to this their level of musicality, their lower weight and better ergonomics, it's all advantages.



Conclusion

The Penon FAN are probably the most fun IEMS I've ever tried from the brand. They are an approach to a more classic V-U profile, but without departing from their own canons. In this way their sound is highly musical, very pleasant, smooth and even passionate. The low end is distinctive, with its depth, power and great texture, making it a very unique and highly enjoyable range. The midrange overlays the typical IEMS V class, offering a superior quality, providing a remarkable level of detail, without omitting or nuancing information. The result is a sweet midrange that borders on lush. And it is in the high end that Penon's nature persists, combining extension with presence to recreate rich, respectful and melodious trebles that allow you to enjoy the music for hours on end. The combination is rounded off by a surprising presentation, with capsule and cable design that enhances the attractiveness of the product, as well as providing great ergonomics and comfort. The result is a clear reference in this category with a superior price/performance ratio.

Short and sweet, just want to share my appreciation on this product.

I bought because of a good coupons from Penon audio (50usd off), so it was my first experience with them, and a took a chance because of their low price.

Surprise when showed off, packaging 9\10, presentation 8.5\10 and good quality overall in term of construction.
Resin, and nice color finish. The driver deliver all what i expect from and iem, but i would say more then what i am getting
use of compare to other Iem's i have in the same price range

This one fall in my top 6....among and i wish to compare with: Fiio Fd1, Shozy Form 1.1, Thieaudio Voyager 3....it place the fan among those.

Overall i give a 9 on 10.

love them

Brief Introduction to Penon Fan
Penon Audio, one of the well-known audio retailer based on Hong Kong, also known as retailer that brings “unknown” brand to international market.
Penon Fan is the latest IEM from Penon Audio, using 10mm full range Dynamic Driver with impedance 23 Ω so it’s supposed to be easy to drive using your phone. Fan Faceplate use stabilized wood panel which remind me to Van Gogh “Starry Night”.
Penon Fan equipped with lot of accessories such as 6 pairs eartips (3 pairs S-M-L green silicone eartips and 3 pairs S-M-L blue silicon eartips, Velour Pouch and exotic wave (or batik) pattern case with tassel and lastly 4-core brown-silver cable.


Sound Quality Evaluation
This Review using YinLuMei A1S as source
High Frequency
Smooth, relaxing with just enough sparkling, airy, good detail, there is Roll-off on upper –treble, non-fatigue, it’s the treble that suitable with any genre

Mid Frequency
A bit recessed, clear mids with a bit warmth touch which make vocal smooth and lush with good weight, still in the realm of neutral. Upper-mid a bit surpressed which make some instrument lacks of “bite” but it’s a fair trade since you get those intimate vocal and sibilant free.

Low Frequency
Deep bass, sub-bass focused, quite impactfull mid-bass, well-controlled, atmospheric, the speed isn’t the fastest DD out there but still a good one.

Separation, Soundstage & Resolution:
Soundstage width is great, depth is decent but could be better. Instrument separation is good. For Resolution just a bit better than average.

Personal Comment
Penon Fan reminds me a lot about Tipsy Dunmer, both of them share the same presentation: warm, relaxed and musical soundsig. Fan is more balanced, better technical and cleaner than Dunmer, not mentioning there is no treble harshness since dunmer can be harsh in some track.

This is my second encounter with Penon IEMs, and I would say Penon really know how to tune relaxing and musical IEM. If "Fan" stands for Fanatic, easily hooked me to become one of their “Fan” for sure.


Should I buy Penon Fan?
If you looking for “Jack of all trade, Master of none” IEM, Penon Fan is the best IEM in this price range. While it won’t do outstanding performance, Fan will do great work for most songs.


That’s all my review of Penon Fan, hope it helps, Cheers~
